Question

我正在学习node.js，但是遇到了问题。我无法以形式in

创建的node.js格式连接到数据库

我根据w3schools教程学习了node.js。我的计算机上安装了MySQL，MySQL中有用户名和密码

My code in the form to connect to the database:

var mysql = require('mysql');

var con = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "2B4jf5@=#[0]@^"
});

con.connect(function(err) {
  if (err) throw err;
  console.log("Connected!");
});

我希望输出为“已连接！”但是

D:\nodejs\node_modules\mysql\lib\protocol\Parser.js:437
      throw err; // Rethrow non-MySQL errors
      ^

Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client
